PROBLEM TO BE SOLVED: To provide an air conditioner for a vehicle, performing dehumidification during heating by suppressing power consumption of a heating means for regeneration.SOLUTION: Outside air having passed through a sensible heat exchanger 30 and inside air dehumidified by a dehumidifier 24 are mixed, and heated by a second cabin heat exchanger 9, at least a part of thus heated air is caused to flow in a regeneration air passage 28 by a second air passage switching means 10 and passes through a regeneration part 25. The heat of the air having passed through the regeneration part 25 is recovered to air to be diffused to the cabin, using a sensible heat exchanger 30, and thus dehumidification heating is performed. As a result, another heating means is not required by using a part of the heated dehumidified air for heating the cabin is used for regeneration of a dehumidification means 26, and since the dehumidified air is used for regeneration of the dehumidification means 26, the regeneration is possible at lower temperature compared with the non-dehumidified air, and power consumption of a heat pump is reduced. Moreover, heat is recovered from the air exhausted to outside to air to be diffused into the cabin, heating load of the second cabin heat exchanger 9 is reduced.
